High resolution measurements of temperature and cloud water, collected duringPhysics of Stratocumulus Top experiment are investigated. Two case studies presented hereillustrate differences between ”classical” stratocumulus capped with a sharp inversion and drylayer above and one type of ”nonclassical” stratocumulus with weak inversion with moist airabove. Entrainment and tranport into the cloud deck are investigated by means of statisticalanalysis of LWC and temperature fluctuations. It comes, that in ”classical” case downdraftswith depleted water content are characterized with reduced temperature (effect of evaporativecooling, presumably negative buoyancy), while in this ”non classical” case such downdraftsare of increased temperature, suggesting that in this case evaporative cooling is not a drivingmechannism of downward transport.
